Because we are stronger together.

At Critical we share a passion for technology and how we can use it to make a difference. Find out more about what life is like at Critical Software.
Inspire. Connect. Grow. This is what working at Critical is all about.

Working at Critical Software will challenge and support you to grow and develop both personally and professionally. You'll be working with a diverse group of people, or should we say superheroes, who are experts at what they do; you'll learn from them and they'll learn from you. 

Critical empowers you to make a difference not only in your work, but also in the communities around us and within the Critical family. We take pride in our charitable initiatives like Critical Fit, which converts our workout hours into donations, and in encouraging people to develop their own projects through FIKALAB, an innovation lab which gives you access to all kinds of gadgets. 

We strengthen our bonds through many moments of fun and inspiration, with meditation workshops, dance classes, summer parties, marathons, team building activities, and even our own bands all playing their part in bringing us together! As well as this, we take every opportunity to open our doors to Critical’s extended family by hosting special event days for our kids and families.

We believe Critical works best when powered by the people around us.

Our footprint

Make the world a safer and better place. Just like real superheroes!

Every day we embrace new missions across industries as diverse as aerospace, space, defence, transport, telecoms, government, energy, finance and healthcare.

Our tech and the millions of lines of code we’ve written have affected the everyday lives of millions of people and we’ve been fortunate to create ground-breaking pieces of engineering that have taken us to places we’d never imagined going.
